Title: Self-propelled type tube testing apparatus
IPC: G01N27/90
Filed: 1976-05-24
Abstract: 1517096 Measuring permeability of tube KETT ELECTRIC LABORATORY 24 May 1976 21400/76 Heading G1N A tube testing apparatus for measuring the degree of carburizing in cracking tubes for an ethylene plant includes a body 4 housing motors 15, one in each of a pair of carriage units 2, 3 driving elastic rollers 16, 17 in each unit. The surfaces of the rollers are shaped to fit the tube. Detectors 5, 6 are fitted to a cylinder 32 mounted on the units 2, 3 and have slide members 33 to maintain them at a fixed distance from the surface of the tube. Each detector includes a detecting coil 24, a non- detecting coil 25 and an energizing coil 23 excited by an oscillator 22. The induced e.m.f. in the non- detecting coil 25 is independent of the degree of carburizing (or permeability) of the tube whilst that induced in the detecting coil 24, in the vicinity of the tube, is dependent on the tube permeability. The coil outputs are rectified in respective circuits 26, 27 from which the signals are fed to a level adjuster 28 which equalizes the levels from the coils when the detecting coil is not in the vicinity of the tube. Carburization of the tube causes an increased output from the differential amplifier 29 feeding an indicator 30 and recorder 31. Actuation of the motors drives the units up the verticallydisposed tube 1. Guider rollers 11, 12 on side surfaces of the units 2, 3 run on the adjacent tube to that which is being monitored by the detectors 5, 6. A limit switch 19 is actuated by a member 20 when the latter strikes the top bend of the tube to halt the motors 15.

Title: Currency Validator
IPC: G07D7/00
Filed: 1967-05-09
Abstract: 1,164,527. Photo-electric currency validation. LITTON INDUSTRIES, Inc. May 9, 1967 [May 16, 1966], No. 21567/67. Heading G1A . In a currency validator, the colour, and, if required, the reflectivity and transmissivity of parts of a banknote are measured photo-electrically to check its authenticity. If the banknote is acceptable, a control signal, to instruct the paying out of coins or dispensing of merchandise, is produced. A banknote 36 is positioned on a transparent plate 52. Light from lamp 44 is directed through the banknote and is received by photo-cells, e.g. cadmium sulphide resistors, 78, 78a &c. located in cavities 80 in detector head 56. The shapes of the cavity apertures correspond with predetermined parts of a particular banknote and thus the transmissivities of these parts are sensed by the respective cells. Photo-resistors 212, 213 are also located on the same side of the banknote 36 as lamp 44 and respectively measure the reflectivity of the banknote and the intensity of the lamp. The measurement of colour is performed by a photo-electric arrangement 201, detailed in Fig. 4 (not shown) as including a lamp (202) illuminating a predetermined area of the note, and photo-cellfilter combinations (203-204, 205-206) measuring the red and green reflected light. These detectors are all connected in the same currency validation circuit, Fig.5 (not shown), which includes a Schmidt trigger producing an "accept" output signal if the banknote is acceptable and a "reject" signal, if the signal representative of the colour, reflectivity and transmissivity of the note is unacceptable beyond a predetermined limit. The photo-resistors 78, 78a &c. are connected in respective parallel arms with variable resistors (140, 140a, &c.) of a bridge circuit, and are balanced against an arm of fixed resistors (103, 104). Also forming an arm of this bridge are photo-cells 212, 213 measuring the reflectance. The sum of the error signals in all the arms of this bridge, which are preset to correspond with an acceptable banknote, is added to the signal from the colour measurement circuit, comprising detectors 203, 205 in association with a bridge rectifier (227-233) and a differential transistor amplifier. The bridge rectifier ensures that only positive error signals are fed to the Schmidt trigger, and rectifier circuitry is provided in the other bridge, comprising calls 78, 78a &c. and 212, 213, for the same purpose. Lamp control circuitry, Fig.6 (not shown), is described, by which the intensities of the lamps (44 and 202) are varied if necessary to allow for different age, cleanliness &c. of a banknote, a further photo-cell (122) being provided to view another predetermined area of the banknote and measure transmissivity of light from lamp 44. Lamp supply voltage fluctuations are also allowed for.

Class 39(1) [Also in Group XL(c)] In an electrostatic recording and reproducing tube in which separate writing and reading beams scan an area of a continuously-moving charge storage target at different times, at different positions of the target and at different speeds, the target is an insulating layer on a metal support which, when bombarded by the high velocity writing beam forms a charge image by the phenomenon of bombardment induced conductivity. In the drawing 2 and 5 are the writing and reading guns which are scanned at different line speeds and at the same line positions over rotating drum 9 which gives the frame movement. The signalmodulated writing beam has an energy of about 10,000 volts, while the reading beam is of constant intensity and causes secondaries to be emitted from the target and collected on the anode of gun 5 to develop an output signal across impedance 8. Drum 9 is an earthed metal body coated preferably by evaporation with an insulating layer about one micron thick of Si O 2  or Mg F 2 . The writng and reading are both effected continuously, The arrangement may be used for changing the number of scanning lines in a television picture without changing frame frequency or synchronization or, if the drum is replaced by a rotating disc, may be used in a P.P. I. radar indicator. An auxiliary gun 10 producing slow flooding electrons may be used for completing the erasure of the charge image and/or for raising the potential level of the signals on the target. The evaporator(s) of the insulating layer on the target may also be included within tube envelope 1. Specification 667,928 is referred to.
